  1. jQuery is a free “Write-Less, Do-More JavaScript Library” that makes it quicker and easier to build JS webpages and write powerful web apps using fewer lines of code. Written in JS, it comes in the form of a single .js file that you link to from your webpage. The JS code then accesses the library by calling various jQuery functions.

  2. How jQuery helps developers: (a) jQuery makes it easy to write powerful JavaScript apps and is great for creating eye-catching animations, Ajax requests, DOM manipulation, image effects, and UI elements; and (b) jQuery lets you easily write cross-browser JavaScript code, avoiding incompatibilities between popular browsers (IE, Firefox, Safari) that otherwise require writing different chunks of JS code for each browser. With jQuery, you just call the appropriate jQuery function and let jQuery deal with making the code run on different browsers.

  3. jQuery has 2 versions to serve 2 purposes: (1) uncompressed .js file is mainly for developers (program development and documentation) who want to see the functions in a readable manner to facilitate modifying or debugging a code; and (2) minified .js file (compact version as all comments / whitespace / unnecessary characters are removed from the file, lightweight) is used for deployment, allowing faster loading when visiting a website and is, thus, what we upload in our web server as it is much quicker for visitors to download.

  1. What is jQuery?
    jQuery is a library with javascript code already written by others. Using jQuery makes coding much more convenient because others have done this already. An example is a log in screen.
  2. How does it help us as developers?
    jQuery helps developers because you can complete problems with ease instead of re-inventing the wheel and recreating it yourself.
  3. Why do we have 2 version of jQuery - minified and uncompressed?
    Uncompressed is the library that tells you everything about the code and minified is what you actually use in your product.

  3. Why do we have 2 version of jQuery - minified and uncompressed?
    4. The uncompressed version has comments and is useful in building a site as to understand how to implement the code but the minimal .js will be used as it is only 23kb compared to the 160kb uncompressed version.

  1. jQuery is a free to use Javascript library which enable programmer to download pre-coded Javascript execution script. It allows user to save time to code something exactly the same common script whereas you can easily download from the library.

  2. It helps developers to save time.

  3. A uncompressed jQuery has a larger file size as it include exactly every line of code. Henceforth it is easily readable. A minified version of jQuery is a compressed file type which removes unnecessary info allowing a smaller file size. The down side is, it will not be as easily readable.

1.jQuery is one of the largest and most widely used javascript libraries.
2. This library can facilitate the creation of various things in javascript such as slideshows, dynamic forms, drop down menus, and enabling a webpage to make multiple requests to the server without reloading the page.
3.The minified version of the library is a significantly quicker download for the user. Although…this was something I didn’t understand in the reading - both of these sizes are in kilobytes. with today’s internet speeds why would it matter if somethnig is 160kb? that’s a negligible download time.

  1. JQuery is a library that makes it quicker and easier to build JavaScript web pages and web apps.
  2. JQuery helps by using code that has already been written. You can use one line of code that’ll grab another set of code that can consist of many lines.
  3. Two versions exists so that the developer may modify code or use code that’ll be quicker to download for the user.

    Allows developers to write a single line of code instead of 20.

  • Why do we have 2 version of jQuery - minified and uncompressed?

  1. Uncompressed = clear, easy to read and modify. However it is very large in size
  2. Minified = has removed all whitespace and unnecessary items making it more difficult to read but far more manageable in size.

  1. jQuery is a library that makes it easier and faster to bould websites and applications on JavaScript. It helps you to accomplish more, with less code.

  2. It helps us to solve common problems in an accessible way. It frees us from having to reinvent the wheel, time after time. While using jQuery you don’t have to worry about browser incompatibilities.

  3. The minified version is a compressed version of the uncompressed one. It’s smaller and only contains the functional minimum in a “non-human-readable-form”. It’s the version you’ll want to use on your website, since it’s much smaller and faster for a user to download.

To provide devs with 2 options. Uncompressed is larger and contains code that is easy to read and modify, whereas the minified version is smaller and easier to download but has a lot of elements removed and therefore can be harder to read. However, minified is usually the version you add to your site as it’s faster to download

What is jQuery?

jQuery is a fast, small, and feature-rich JavaScript library*.

Definition: jQuery Official Website

How does it help us as developers?

jQuery has brought a lot of features but mostly known as better selection methodology to the DOM elements and helps user to build shorter, quick and clean javascript. It also is versitile and extensible.

Why do we have 2 version of jQuery - minified and uncompressed?

Uncompressed version of libraries might be useful for different reasons like for debugging, developing, learning how it is working. The issue is actually the minified versions. Minified codes are cleaned out of comments and spaces, has shrinked names of variable and functions in order to gain more space in the document and reduce the loading times for the browsers. It is totally against of ‘Clean Code’ concept but a library especially with its global-usage-features they need to be developed so long and they grows a lot that matters storage and speed issues.
